Description

Die Erfindung betrifft eine Vorrichtung zum Einrichten einer Wirbelsäule mit geschädigten Wirbelkörpern, wobei Tragbolzen in die Wirbelkörper beiderseits des geschädigten Wirbelkörpers eingesetzt sind, um ein Stützsystem anzubringen.The invention relates to a device for setting up a spine with damaged vertebral bodies, supporting bolts being inserted into the vertebral bodies on both sides of the damaged vertebral body in order to attach a support system.

Bekanntlich muß einer Wirbelsäule mit beschädigten Wirbelkörpern dadurch wieder zur Stabilität verholfen werden, daß ein Stützsystem in die Wirbelkörper beiderseits des geschädigten Wirbelkörpers eingesetzt wird. Dabei muß zunächst ein Einrichten und daraufhin das Stabilisieren der Wirbelsäule erfolgen. Es ist schon eine Vorrichtung gemäß DE-A-3 219 575, die auf den selben Erfinder zurückgeht wie der Gegenstand der vorliegenden Anmeldung, bekannt. Das Stabilisieren der Wirbelsäule erfolgt dabei in der Weise, daß der geschädigte Wirbelkörper mechanisch überbrückt wird. Hierzu dienen Spannschrauben, die die übereinanderstehenden Tragbolzen, die in die gesunden Wirbelkörper eingesetzt sind, miteinander verbinden und dadurch die Kraftübertragung übernehmen. Die Spannschrauben bestehen aus einer Gewindehülse, in deren Enden Schraubbolzen mit gegensinnigen Gewinde eingeschraubt sind. Dadurch kann die die Tragbolzen verbindende Spannschraube durch Drehen der Gewindehülse zum Einrichten und zum Stabilisieren verwendet werden.As is known, a spine with damaged vertebral bodies must be restored to stability by inserting a support system into the vertebral bodies on both sides of the damaged vertebral body. First you have to set up and then stabilize the spine. A device according to DE-A-3 219 575, which goes back to the same inventor as the subject of the present application, is already known. The spine is stabilized in such a way that the damaged vertebral body is bridged mechanically. For this purpose, clamping screws are used, which connect the superimposed supporting bolts, which are inserted into the healthy vertebral bodies, and thereby take over the power transmission. The clamping screws consist of a threaded sleeve, in the ends of which bolts with opposite threads are screwed in. As a result, the clamping screw connecting the supporting bolts can be used for setting up and stabilizing by turning the threaded sleeve.

Da zum Einrichten der Wirbelsäule wegen der erforderlichen Hebelkräfte relativ lange Tragbolzen benötigt werden, muß nach erfolgter Stabilisierung der Wirbelsäule ein Abschneiden der überstehenden Längen der Tragbolzen erfolgen, damit die Implantation des gesamten Stützsystems erfolgen kann. Das bringt jedoch Erschütterungen dieses Systems mit sich ; außerdem ist unvermeidlich, daß Metallstaub in die Wunde gelangt. Hinzukommt, daß das Stützsystem eine große Materialmenge darstellt, die implantiert werden muß. Außerdem ist die Operation wegen der Vielzahl der in der Tiefe der Wunde einzusetzenden Schrauben technisch schwierig und erhöht die Operationsdauer.Since relatively long support bolts are required to set up the spine because of the required lever forces, the protruding lengths of the support bolts must be cut off after stabilization of the spine so that the entire support system can be implanted. However, this brings shocks to this system; it is also inevitable that metal dust will get into the wound. In addition, the support system represents a large amount of material that must be implanted. In addition, the operation is technically difficult due to the large number of screws to be inserted in the depth of the wound and increases the duration of the operation.

In bezug auf das bloße Einrichten einer Wirbelsäule ist eine Vorrichtung nach der polnischen Druckschrift PL-A-96 695 bekannt, wobei es dort nur darum geht bei einer an sich gesunden, aber gekrümmten Wirbelsäule die Krümmung durch einen Distraktionsstab nach und nach zu beseitigen, indem verstellbare Arme, die über entsprechenden Zapfen und Hackenhalter auf in die Wirbelsäule eingesetzte Hacken wirken, mit Hilfe eines Zahnradgetriebes verstellt, und zwar auseinandergezogen werden, damit die Krümmung beseitigt wird. Diese Vorrichtung reicht aber wegen ihrer begrenzten Bewegungsfreiheit für die Belange des Ausrichtens einer durch Verletzung fehlstehenden Wirbelsäule nicht aus.With regard to the mere setting up of a spine, a device according to the Polish publication PL-A-96 695 is known, the only purpose of which is to gradually remove the curvature by means of a distraction rod in the case of a healthy but curved spine adjustable arms, which act on the pegs inserted into the spine via corresponding pegs and peg holders, are adjusted with the aid of a gear mechanism and are pulled apart so that the curvature is eliminated. However, because of its limited freedom of movement, this device is not sufficient for the purposes of aligning a spine that is missing due to injury.

Der Erfindung liegt daher die Aufgabe zugrunde, das Einrichten der Wirbelsäule mit anderen Mitteln vorzunehmen, als denen, die zur Stabilisierung dienen.The invention is therefore based on the object of carrying out the setting up of the spine by means other than those which serve for stabilization.

Nach der Erfindung besteht die Vorrichtung aus einem ersten auf einer Führungsachse verstellbaren und einen zweiten auf der Führungsachse ortsfesten Arm, und ist dadurch gekennzeichnet, daß jeder Arm endseitig eine um zwei senkrecht zueinander stehende Achsen frei verstellbare Aufnahmehülse trägt, die je eine Verlängerungsstange aufnimmt, die auf den Tragbolzen abnehmbar aufgesetzt ist, der in den Wirbelkörper angebracht ist, und daß jeder Tragbolzen eine Befestigungsfläche für einen zwischen den Tragbolzen einspannbaren Fixierstab, z. B. eine Spannschraube, aufweist.According to the invention, the device consists of a first adjustable on a guide axis and a second fixed on the guide axis arm, and is characterized in that each arm carries at the end a freely adjustable about two mutually perpendicular axes receiving sleeve, each of which receives an extension rod which is detachably placed on the support bolt, which is attached in the vertebral body, and that each support bolt has a fastening surface for a fixing rod which can be clamped between the support bolts, e.g. B. has a clamping screw.

Im einzelnen ist die Ausbildung dabei so getroffen, daß die Aufnahmehülse eine Ansatzfläche mit Rasterung trägt, die auf einer Stützfläche mit Rasterung lösbar befestigt ist, wobei die Stützfläche gelenkig und feststellbar am Arm angebracht ist. Dadurch kann zunächst die Stützfläche um die Gelenkachse verstellt werden, außerdem kann auch die Ansatzfläche mit ihrer Rasterung auf der Stützfläche selbst verstellt werden. Die Befestigung der Ansatzfläche mit der Stützfläche erfolgt dabei im allgemeinen durch eine Schraubverbindung, wobei dann in der Ansatzfläche eine entsprechende Bohrung angebracht sein muß.Specifically, the design is such that the receiving sleeve carries an attachment surface with a grid that is releasably attached to a support surface with a grid, the support surface being articulated and fixable on the arm. As a result, the support surface can initially be adjusted about the hinge axis, and the attachment surface with its grid on the support surface itself can also be adjusted. The attachment of the attachment surface to the support surface is generally carried out by a screw connection, in which case a corresponding hole must then be made in the attachment surface.

Die Führungsachse, auf der die beiden Arme angebracht sind, trägt ein Gewinde, das eine Stellmutter aufnimmt, die an dem verstellbaren Arm angreift.The guide axis on which the two arms are attached carries a thread which receives an adjusting nut which engages on the adjustable arm.

Sind die Verlängerungsstangen auf die Tragbolzen aufgesetzt, dann kann das Einrichten der Wirbelsäule dadurch erfolgen, daß die Vorrichtung mit Hilfe der Aufnahmehülsen auf die Verlängerungsstangen aufgeschoben und dort befestigt wird. Durch Drehen an der Stellmutter werden die beiden Arme aufeinanderzu- oder wegbewegt, so daß auf die Tragbolzen ein entsprechendes Biegemoment ausgeübt wird, das zu einer Einrichtung bzw. Ausrichtung der Wirbelsäule führt.If the extension rods are placed on the support bolts, the spine can be set up by pushing the device onto the extension rods using the receiving sleeves and fastening them there. By turning the adjusting nut, the two arms are moved towards or away from each other, so that a corresponding bending moment is exerted on the supporting bolts, which leads to the spine being set up or aligned.

Der Tragbolzen trägt koaxial ein Gewinde zur Befestigung der Verlängerungsstange. Ferner trägt der Tragbolzen eine Befestigungsfläche für eine Spannschraube.The support bolt has a coaxial thread for attaching the extension rod. Furthermore, the support bolt carries a mounting surface for a clamping screw.

Ist das Einrichten der Wirbelsäule erfolgt, dann kann durch Anbringen einer Spannschraube oder eines Fixierstabes zwischen den mit Rasterung versehenen Befestigungsfläche der beiden Tragbolzen die Stabilisierung der Wirbelsäule erfolgen. Da die Verlängerungsstangen abnehmbar sind, kann mithin der Tragbolzen relativ kurz ausgebildet werden, da er nämlich nicht zum Einrichten der Wirbelsäule benötigt wird, sondern lediglich zur Stabilisierung. Es kann dann auch eine Spannschraube verwendet werden, die nicht aus einer Gewindehülse mit zwei endseitig eingesetzten Schraubbolzen besteht, sondern lediglich eine Spannschraube aus Spannhülse und Schraubbolzen, die jeweils endseitig eine Befestigungsfläche mit Rasterung aufweisen, um an die Befestigungsflächen der Tragbolzen angesetzt zu werden.Once the spine has been set up, the spine can be stabilized by attaching a tensioning screw or a fixing rod between the fastening surface of the two support bolts provided with a catch. Since the extension rods are removable, the support bolt can therefore be made relatively short, since it is not needed to set up the spine, but only for stabilization. It is then also possible to use a clamping screw which does not consist of a threaded sleeve with two screw bolts inserted at the end, but only a clamping screw made of clamping sleeve and screw bolts, each of which has a fastening surface with a catch at the end in order to be attached to the fastening surfaces of the supporting bolts will.

Damit wird deutlich, daß zum Einrichten der Wirbelsäule eine besondere Vorrichtung verwendet wird, die nach erfolgter Einrichtung abgenommen werden kann, wobei ein Absägen der Tragbolzen nicht erforderlich ist, da die Verlängerungsstangen abnehmbar an den relativ kurzen Tragbolzen angebracht sind.This makes it clear that a special device is used to set up the spine, which can be removed after installation, sawing off the support bolts is not necessary because the extension rods are detachably attached to the relatively short support bolts.

Die Arme sind winkelförmig und räumlich gekrümmt ausgebildet. Dadurch ist das Operationsfeld leichter zugänglich, weil sich die Arme von der Wunde weg erstrecken.The arms are angular and spatially curved. This makes the surgical field more accessible because the arms extend away from the wound.

In der Zeichnung ist eine beispielsweise Ausführungsform dargestellt.

  • .. Fig. 1 zeigt die erfindungsgemäße Vorrichtung in Ansicht ;
  • Fig. 2 zeigt schematisch die Anordnung der Vorrichtung an den Tragbolzen, die in den Wirbelkörpern angebracht sind ;
  • Fig. 3 zeigt einen Schnitt gemäß der Linie III-III.
An example embodiment is shown in the drawing.
  • .. Fig. 1 shows the device according to the invention in view;
  • Fig. 2 shows schematically the arrangement of the device on the support bolts which are attached in the vertebral bodies;
  • Fig. 3 shows a section along the line III-III.

Wie Fig. 1 zeigt, besteht die Vorrichtung aus einer Führungsachse 4, auf der der Arm 5 verstellbar und der Arm 11 ortsfest angebracht sind. Zum Zwecke der Verstellung ist die Führungsachse 4 mit dem Gewinde 4a versehen, auf der eine Stellmutter 6 angebracht ist, die an dem Arm 5 angreift. Dadurch kann der Abstand der Arme 5 bzw. 11 durch Drehen an der Stellmutter 6 verändert werden. Am Ende der Arme ist je eine Aufnahmehülse 9 um zwei Achsen verstellbar angebracht. Die Ausbildung ist dabei so getroffen, daß die Aufnahmehülse 9 eine Ansatzfläche 13 mit Rasterung aufweist, die auf der Stützfläche 8 lösbar mittels der Schraubverbindung 10 befestigt ist. Die Stützfläche 8 besitzt dabei eine Buchse 16, die auf einem entsprechenden Zapfen, der am Armende angebracht ist, gelenkig angeordnet ist. Das Feststellen der Hülse 16 geschieht mit Hilfe einer Schraube 14 oder dergleichen, sofern es erforderlich sein sollte. Somit kann die Aufnahmehülse 9 um die Achse 15 und außerdem noch um die Achse 14 geschwenkt werden. Die Ausbildung an dem Arm 11 ist die gleiche.As shown in Fig. 1, the device consists of a guide axis 4 on which the arm 5 is adjustable and the arm 11 are fixed in place. For the purpose of adjustment, the guide axis 4 is provided with the thread 4a, on which an adjusting nut 6 is attached which engages on the arm 5. As a result, the distance between the arms 5 and 11 can be changed by turning the adjusting nut 6. At the end of the arms, a receptacle 9 is adjustably mounted around two axes. The design is such that the receiving sleeve 9 has an attachment surface 13 with a grid, which is detachably fastened on the support surface 8 by means of the screw connection 10. The support surface 8 has a socket 16 which is articulated on a corresponding pin which is attached to the arm end. The sleeve 16 is fixed with the aid of a screw 14 or the like, if it should be necessary. Thus, the receiving sleeve 9 can be pivoted about the axis 15 and also about the axis 14. The formation on the arm 11 is the same.

Der Arm 5 bzw. 11 ist etwa winkelförmig ausgebildet und außerdem noch räumlich gekrümmt, damit das Operationsfeld möglichst leicht zugänglich ist.The arm 5 or 11 is approximately angular and also spatially curved so that the operating field is as easily accessible as possible.

Die Fig.2 zeigt die Handhabung der Vorrichtung. In die gesunden Wirbelkörper 3 ist in an sich bekannter Weise der Tragbolzen 17 eingeschraubt. Er besitzt am Ende eine Vertiefung 18 mit Innengewinde, damit die Verlängerungsstange 12 darin eingeschraubt werden kann. Das Gewinde liegt mithin koaxial zum Tragbolzen 17. Seitlich von dem Tragbolzen 17 ist eine Befestigungsfläche 19 mit einer Rasterung 20 angebracht, damit die beiden Tragbolzen zum Zwecke der Stabilisierung der Wirbelsäule durch eine Spannschraube 21 miteinander verbunden werden können. Diese Spannschraube besteht aus einem Gewindebolzen 22 und einer Gewindehülse 23 (Fig.3).2 shows the handling of the device. The supporting pin 17 is screwed into the healthy vertebral body 3 in a manner known per se. It has a recess 18 with an internal thread at the end, so that the extension rod 12 can be screwed into it. The thread is therefore coaxial with the support bolt 17. A mounting surface 19 with a catch 20 is attached to the side of the support bolt 17 so that the two support bolts can be connected to one another by means of a clamping screw 21 for the purpose of stabilizing the spine. This clamping screw consists of a threaded bolt 22 and a threaded sleeve 23 (Fig.3).

Ist mit Hilfe der Vorrichtung die Wirbelsäule eingerichtet, dann erfolgt die Stabilisierung mit Hilfe der Spannschraube 21. Als dann können die Verlängerungsstangen 12 abgenommen werden. Da mithin relativ kurze Tragbolzen zur Anwendung kommen können, ist ein nachträgliches Absägen dieser Bolzen nicht erforderlich, denn sie sind leicht in die Muskulatur implantierbar.If the spine is set up with the aid of the device, the stabilization takes place with the help of the tensioning screw 21. The extension rods 12 can then be removed. Since relatively short carrying bolts can therefore be used, it is not necessary to subsequently saw these bolts off, since they can easily be implanted into the muscles.
